“…As such, the majority of commensal studies in the Pacific, particularly those using archeological specimens, have targeted fragments of 100-600 bp in the mitochondrial control region (e.g., Barnes et al, 2006;Larson et al, 2007;Storey et al, 2007Storey et al, , 2010Oskarsson et al, 2012). As ancient DNA is highly fragmented, it is practical to target fragments of the mitochondrial control region that produce the most usable variation.…”

The location of the immediate eastern Polynesian origin for the settlement of Easter Island (Rapa Nui), remains unclear with conflicting archeological and linguistic evidence. Previous genetic commensal research using the Pacific rat, Rattus exulans; a species transported by humans across Remote Oceania and throughout the Polynesian Triangle, has identified broad interaction spheres across the region. However, there has been limited success in distinguishing finer-scale movements between Remote Oceanic islands as the same mitochondrial control region haplotype has been identified in the majority of ancient rat specimens. To improve molecular resolution and identify a pattern of prehistoric dispersal to Easter Island, we sequenced complete mitochondrial genomes from ancient Pacific rat specimens obtained from early archeological contexts across West and East Polynesia. Ancient Polynesian rat haplotypes are closely related and reflect the widely supported scenario of a central East Polynesian homeland region from which eastern expansion occurred. An Easter Island and Tubuai (Austral Islands) grouping of related haplotypes suggests that both islands were established by the same colonization wave, proposed to have originated in the central homeland region before dispersing through the south-eastern corridor of East Polynesia.

“…These expected human diet values are consistent with the consumption of a mixed diet involving at least three dietary components.

A B S T R A C TBoth archaeological and isotopic data document dietary changes over the first five centuries of Western Pacific island settlement, a time period beginning with the Lapita expansion about 3000 years ago. This change is marked by a decrease in marine food intake and an increase in vegetal food intake occurring in the Late Lapita/ immediately post-Lapita populations. The recent discovery of human burials at Talasiu (~2700-2600 cal. BP) in the Kingdom of Tonga opens new opportunities to assess this matter. We characterize the nature of the food items consumed by the Talasiu humans (n = 21) using collagen and apatite carbon and nitrogen stable isotope ratios. We conducted an intra-Pacific comparison to examine the use of marine resources and the contribution of horticultural products and to look at the homogeneity of dietary practices within the Tongan group. Isotope results indicate a mixed diet of terrestrial and marine resources including a differential contribution of more specific marine foods (e.g., non-reef fish/inshore fish and shellfish). The Talasiu dietary pattern appears closer to that of the early Lapita population of Teouma than to other Late Lapita populations suggesting a different pattern of dietary change at the eastern end of the Lapita distribution. The slower rate of change may be due to the small size of both the island and the population, and also the additional potential role of social or cultural factors.

“…As a result, they provide an opportunity to study colonization events and subsequent movements for islands and regions where they were successfully introduced, especially through the use of biomolecular techniques, including ancient DNA. In the AsiaPacific region, the complex histories of Pacific island colonizations have been investigated using the biological elements associated with these cultures, such as bottle gourds (7,8), sweet potatoes (9), pigs (10,11), dogs (12), Pacific rats (13), and chickens (14)(15)(16)(17). However, studies of commensals and domesticates in the Pacific to date have provided limited resolution of dispersal routes, due to low amounts of genetic diversity in many groups and overwriting of genetic signals by subsequent introductions, especially for cotransported species like rats (10,13,18).…”

“…Previous studies of modern and ancient chickens have identified both haplogroup D and E in the Pacific (14)(15)(16)(17)26), making interpretation of colonization history difficult due to potentially contrasting origins and dispersal histories (24). Indeed, the presence of haplogroup E in the Pacific has been used to infer a link between Polynesia and pre-Columbian South America, although both the phylogenetic signal and radiocarbon dating of the samples have been questioned (27)(28)(29).…”

Significance Ancient DNA sequences from chickens provide an opportunity to study their human-mediated dispersal across the Pacific due to the significant genetic diversity and range of archaeological material available. We analyze ancient and modern material and reveal that previous studies have been impacted by contamination with modern chicken DNA and, that as a result, there is no evidence for Polynesian dispersal of chickens to pre-Columbian South America. We identify genetic markers of authentic ancient Polynesian chickens and use them to model early chicken dispersals across the Pacific. We find connections between chickens in the Micronesian and Bismarck Islands, but no evidence these were involved in dispersals further east. We also find clues about the origins of Polynesian chickens in the Philippines.
